Question

2. B = {(Rizal, 1861), (Bonifacio, 1863), (Mabini, 1864), (Luna. A., 1866), (Del Pilar
G., 1875) D(B)
3. If the ordinates of A are (Quezon, Cavite, Rizal, Batangas, Laguna) and its absciss
are each provinces' corresponding Capitals, what would be the domain of (A)?​

Answer 1

Given : the ordinates of A are {Quezon, Cavite, Rizal, Batangas, Laguna} and its abscissa  are each provinces corresponding Capitals

To Find : domain of (A)

Solution:

abscissa  = x

ordinates  = y

x  represent  Domain

y represent  range  

Range of A =   {Quezon, Cavite, Rizal, Batangas, Laguna}

Domain of  A ={ capitals of Quezon, Cavite, Rizal, Batangas, Laguna}

each provinces corresponding Capitals  would be domain of A

Thus, domain of A = {Lucena, Imus, Batangas City, Santa Cruz}

B = {(Rizal, 1861), (Bonifacio, 1863), (Mabini, 1864), (Luna. A., 1866), (Del Pilar

G., 1875)

D(B) = { Rizal , Bonifacio,  Mabini , Luna , Del Pilar  G)
